Lenspen

Someone gave me a Lenspen for a gift. It is meant to be used to clean the glass on lenses and filters. Before I start using it on all of my expensive lenses, I wanted to know if any of you had used it, did it do a good job, and most importantly, is it safe to use on expensive equipment.

Thanks for any information you can provide to me.

I have a Lenspen. I use the brush end all the time. I've used the other end on filters with no problems but I don't trust it on expensive optics.

I use it regularly since more than 3 years on all of my lenses. Just be sure that first of all you blow away all sand and then use first the brush - blow again - and then start cleaning with the other end. I use the same system from the same company - LensKlear - for cleaning my sensor ;)

I have one and use it sometimes. When cleaning your lens hold it so the glass is pointed downward (gravity assist) and blow off any loose particles before using the brush. I have used the other end with no harm to the filter or lens but it should be needed rarely. Unless they are quite large, opaque particles on the lens have almost no effect of image quality http://kurtmunger.com/dirty_lens_articleid35.html. What will affect your image is water on the lens because it is transparent and has the effect of altering the shape of the lens. My preferred method for lens cleaning is a clean microfiber cloth which are readily available.

I have a couple of them and use them all the time. I do definitely remove any loose debris first.

And if you happen to get a small scratch, I also wouldn't worry too much about it - 99% of them will never show up in an image anyway. Similar to what Jim posted, here's another little experiment showing how even fairly large scratches probably won't show in a lot of images.

I've used LensPens for about 10 years now with absolutely no problems - no scratching of coatings, etc. I wouldn't dream of going out without one.

I bought one 3 months ago, I had my doubts for the longest time, wouldn't do without now, use the brush first to get the particles off then the other end. Works great.

Thanks everyone. I decided to give it a try and am very impressed with the results.

I've been carrying one in my pack for several years and have never had a problem with it. Works great on lenses and filters.
